To all whom it mlay concern;-

Be it known that I,'TH0MAs W. Frren, J r., a citizen of the UnitedStates of America, re-* siding at Cleveland, in the county of Cuyahogaand State of Ohio, have invented certain new and useful Improvements inTrack- Brakes; and I hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it pertains to make-and use the same.

This invention relates to an improved track-brake which is supported andarranged adjacent to therail of a track for the purpose of arresting acar or vehicle moving upon and along the said track by exerting ressureagainst both faces of, and thereby c amping the wheels which engage, thesaid rail.

e To the end of providing a simple and effective brake of thecharacterindicated and to realize other advantages hereinafter appearing thisinvention-consists in certain features of construction and combinationsof parts hereinafter described, and pointed out in the claims. I

In the accompan ing drawings, Figu're 1 is a top plan of one ofltherails'of a track upon and along which cars or vehicles are ril'evedandillustrates the forward wheel of a car in position to further segaratethe pressure-exerting or clamping brake. Fi 2 is a side elevation insection on line 2 2fi ig. 1, lookin in the direction indicated by thearrow. ig. 3 is a transverse vertical section on any one of lines 3 3,Fig. 2, looking in the direction indicated by the arrow. F1 4 is atransverse vertical sec-' tion correspon ingwith Fig. 3, except that inFig. 4 the clamping-bars are shown actuated laterally and outwardlyagainst the action of means acting to retain the said bars in theirinner and normal position.

Referring to the drawings, A represents a rail of a track, and B asleeper instrumental in supporting the said rail and arranged next belowand longitudinally of the rail.

D indicates a portion of the wheel of a car mounted on the trackcomprising therail A, and G two"'pressure-exerting or clamping barsadapted to exert pressure against oppo-. site faces, respectively, ofthe W eels at one ars of my improved .-ranged transversel and the sameside of the car, which bars are arranged, therefore, asuitable distanceabove,

but at opposite sides of, the rail. The barsG extend longitudinallyofthe rail Aa suitable distance. Each bar G 'isfrovided at its uperlongitudinal edge an externally with a aterally and outwardly projectingflange g,

Which extends from end to end 0 and reinforces the bar. The bars G aremovable laterally-that is, the bars G are relatively movable to Widenthe space between them, because the said bars are normally spaced apartsomewhat less than the thickness of the wheels which are to be clampedby and between the said bars. Means acting to retain the bars G in theirinner and normal position are pro- ;vid'ed, and the said bars curvelaterally and outwardly at their ends, as at Gthat is, the

end portions of thebars G diverge toward the outer extremities 'ofthesaid end portions to accommodate the passa e between the bars of theforward wheel of the wheels at one and the same side of the car and toaccommodate the movement of the-said bars laterally and outwardly by thesaid forward wheel against the action of the means acting to retain thebars in their normal position upon the travel of the said wheel betweenand along the said bars. Preferably several upright lever-forming bars Kare arran ed at the outer side of each bar G and equidistantlylongitudinally of the last-mentioned bar. Each upright lever-forming barK is secured at its upper end in any approved inanner to the adjacentclamping-bar G and extends downwardly from the said clamping member toand transverselyof the adjacent side of the sleeper B and is looselymounted at its lower end upon a bolt L, which is arranged horizontallyand at a right angle to the sleeper and extends laterally throu h andtransversely of the lower portion 0% the sleeper. It will beobserved,therefore, that several parallel bolts L are'supported from the sleeperB and arof and equidistantly spaced longitudina ly of the sleeper. Thebolts L project a suitable distance beyond op osite sides of the sleeperB, and each bolt L ears a pair of lever-forming bars K, which areloosely mounted on the bolt at op osite, sides, respectively, of thesleeper, an each I 5 outer side of one of the washers bar K is arrangedbetweenapair of washers J, which are loosely mounted on the said bolt,with the inner washer of each pair of washers arranged next adjacent theadjacent side of the sleeper, with the outer washer of one of the pairsof washers J interposed between the outer side of one of the bars K andthe head 1, with which the bolt is provided, and

with the outerwasher of the other pair of wash- 1 ers J interposedbetween the outer side of the other of the said bars and a nut e mountedon the shank of the bolt. In other words, each bolt L between thewashers of each pair of washers J extends loosely through holes 7c,

I5 formed in the lower ends of the bars K,

mounted on the said bolt to render the said bars ca able of being swunoutwardly to widen t espace between the clampin -bars G, and the pair ofbars K, supported om the 2 said bolt, are arranged at opposite sides,re-

spectively, of the sleeper.

The opposin faces or sides of the washers of each pair 0 washers Jrecede from each other outwardly from the bolt u on which the saidwashers are mounted to t e edges of the washers to render thelever-forming bars K free to swing laterally, and the sleeper Bconstitutes means for limiting the movement of the clamping-bars Ginwardly or toward 3 each other, and the holes is in the bars K on eachbolt L are large enou h to freely accommodate the said swinging o thesaid bars laterally. At an suitable point between each ho t L and t eclamping-bars G is provided 3 5 another bolt R, which extends looselythrou h the lever-forming bars K, mounted on t 1e aforesaid bolt L. Thebolts L and R are parallel, and the bolts R extend beyond the outersides of the lever-formin bars K. The

4 bolts R are shown extending t ough slots 0/ in the rail A. Two washersQ are loosely mounted upon each bolt R at the outer side of the op ositebars K, respectively connected with t e said bolt, and the op osingfaces or sides of the said washers rece e from each their inner andnormal osition.

Obviously the forwar car-wheel, which, as shown in Fi 1, comes intoengagement with the inner si es of adjacent diverging ends of theclamping-bars G, actuates the said bars during the movement of the saidwheel into the space between the said bars against the action of thesprings h, confined on the bolts R.

By the construction hereinbefore described it will be observed that thewheels at one and 5 3 the same side of the car when they are in pobarsarranged above and longitudinall sition between the two pressure-exertinor clamping bars G are effectually clampe by and between the said bars.
